292 The Management and Diseases of the Dog. 



with serous fluid ; and it sometimes happens during life 

 from inflammation being created in the substance of the 

 tumour, that this cystic fluid becomes purulent, the sac 

 ruptures, and degenerates into a common, unhealthy, sub- 

 acute abscess. Excision is, even under the circumstances,, 

 still advisable ; for even if we get it healed, and the tumour 

 still remains, absorption is out of the question. Fibro- 

 cystic tumour is usually present in " capped elbows." 

 Removal by excision is simple, and is followed by no ill 

 effects. When they occur in connection with the hocks it 

 is more advisable to use outward applications. I have 

 found iodine the best agent. 



Calcareous Tumour. — This description of tumour is most 

 frequently found in the vicinity of glands. In the dog, 

 it is generally seen in connection with the fibrous tumour 

 of the mammary gland. In long-existing cases, the lattei 

 is often entirely supplanted by the former. 



Treatment. — As in the two former, excision is the only 



tissue, intermixed with a few fibres of yellow elastic tissue. Besides 

 the cyst which Mr. Gowing punctured, there was another of equal size 

 which contained about four ounces of fluid, having the appearance of 

 pus slightly tinged with blood. This fluid, under the microscope, was 

 found to contain a large quantity of cholesterine, with exudation- 

 corpuscles and blood-discs. In the interior of the cyst which was last 

 opened, there was a small detached tumour of the size of a chestnut, 

 smooth oh the surface, and quite firm in texture. To the interior of 

 the walls of the two cysts were attached small tumours, varying in 

 size from a pea to a hazel-nut, and on the surface of the lining of the 

 cysts a quantity of flocculent white matter was deposited." 



Three accompanying m croscopic illustrations are given, to convey 

 an idea of the structure of the morbid growths, which were all com- 

 posed of the same elements. It is further observed : " It is obvious 

 that the morbid growth originated in disease of the structures of the 

 true skin, probably the result of an injury." 



I recently removed a fibro-cystic tumour the size of a hazel-nut from 

 a fore-toe of a small black-and-tan terrier. Placing a ligature round 

 close to its attachment, I drew it sufficiently tight to sever it at once ; 

 the hsemorrhage, which was excessive for the situation, I stayed with 

 cautery.
